HENRY SMITH, OF SOUTHINGTON, CONNECTICUT.

Letters Patent No. 90,401, dated May, 25, 1869.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, HENRY SMITH, of Southington, in the county ofHartford, State of Connecticut, have invented a new and improvedFlue-Stopper and Ventilator; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will I enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, making a part of this specification, inwhich- Figure 1 is a front elevation of my invention.

Figure 2 is a side elevation of the same.

Figure 3 is a side elevation of one of the sockets and springs.

Similar letters of reference indicate like parts.

My invention consists in securing the springs of a flue-stopper to thebody of the same, by providing it with suitable sockets, to receive theends of the springs, and hold the same when in use, and from whichsockets the springs can be withdrawn for transportation.

'0' c c designate springs, which, when in place, bear against the insideof the chimney-flue, and hold the stopper in its place in the usualmanner.

d designates a socket, secured to the back of the stopper, in any propermanner The inside of the socket d is of the size and shape of the end ofthe springs 0 c c.

The stopper, with its register a, and the sockets d secured to it, isready for transportation, and the springs c c 0 can be formed and packedwith the same, and so remain until it is desired to use the stopper,when the springs c c a can be inserted in the sockets d.

Ordinarily, flue-stoppers are not kept on hand for sale, but are made toorder as wanted, or if a few are sometimes made beforehand, they aresold to the consumer at the same shop where they are made. If eachtinner or stove-dealer should attempt to make a register in the fewflue-stoppers sold by him, making them in such limited quantities wouldmake the cost so high as to prevent their ready sale.

By making the springs removable, as in my invention, so that thestoppers can be transported for sale, a large quantity can be made-atone time, and suitahle machinery provided for making the same, so thatthey can be furnished with a register for nearly, if not quite as low aprice as the ordinary stoppers made by hand.

Registers have been used in stove-pipe thimbles to ventilate rooms,which thimble was secured firmly to the chimney, and the register usedeither when the pipe was in the chimney or not, but my stopper is onlyto place in the pipehole when the pipe is withdrawn, and cannot be usedsimultaneously with the pipe.

The register a will be found very convenient for ventilation in summer.

I do not claim holding a stopper in its place by springs, as it is thecommon manner of holding the same; but the springs of common ones aresoldered or riveted to the stopper, and therefore so bulky as to forbidtransporting the stopper to sell.

What I claim as new, and desire to secure by Letters Patent, is-- Thecombination of the socket (1, spring 0, and register a, the wholecombined and arranged with a fluestopper, substantially as described,and for the purposes herein set forth.
